• A ball is dropped from rest from the top of a building. Two motion detectors which are positioned outside of two different windows, one above the other, record the velocities of -15.5 m/s and -17.2 m/s as the ball goes past them. (no air resistance).
• a. How far apart are the motion sensors mounted?
• b. How far from the top motion sensor is the top of the building where the ball was released?
